Corbin Russwin 606K79 57A2 626 – Frequently Asked Questions

1) Is the Corbin Russwin 606K79 a complete mortise cylinder or just the plug?
It is the plug only. The 606K79 is a 7-pin Individual X Class cylinder plug meant to go into a 3 inch Corbin Russwin mortise cylinder shell, so it is a re-keying and rebuild part rather than a drop-in cylinder. If you need a complete assembled mortise cylinder to put in a door, buy the cylinder, not the plug. A complete unit from another brand would be something like the Detex MC65 mortise cylinder, a 1-1/8 inch 6-pin cylinder cut to Schlage C keyway, or the Adams Rite 4036 five-pin mortise cylinder.
2) Will the 606K79 plug work in my existing Corbin Russwin keying system?
Only if your system runs the 57A2 keyway. The plug is cut for 57A2 and keys from any other Corbin Russwin section will not enter it. Check the keyway stamp or your keying schedule first, because a plug in the wrong section is not something you can correct at the bench.
3) Does the 606K79 plug fit a 1-1/8 inch mortise cylinder?
No. This plug is sized for 3 inch mortise cylinders. A 1-1/8 inch shell takes a shorter plug, so for that length you need the part matched to it. If you are working on a 1-1/8 inch opening and want a finished cylinder instead of a rebuild part, the Detex MC65 is a 1-1/8 inch 6-pin mortise cylinder.
4) Is the 606K79 plug an interchangeable core, or do I need something like a BEST core?
The 606K79 is an individual 7-pin plug for a 3 inch Corbin Russwin mortise cylinder - it is pinned and installed into a cylinder body, not pulled and swapped with a control key. For a true interchangeable core setup, the BEST 1CB Peaks 150 Series interchangeable core cylinder or the BEST 1CDF drill resistant patented 7-pin brass 150 Series core are removable cores; the BEST 1C5 is a standard 5-pin core. Schlage's 20-057 is a 6-pin full size interchangeable core rim cylinder if the opening uses FSIC housings.
5) My opening is a rim exit device, not a mortise lock. What cylinder do I use there?
The 606K79 plug is built for 3 inch mortise cylinders, so it is the wrong format for a rim device. Rim applications are served by the Schlage 20-021 6-pin rim cylinder with a vertical tailpiece cam or the 20-022 with a horizontal tailpiece cam, depending on which orientation the device requires. The BEST 12E Series dummy rim cylinder at 1-5/32 inch diameter covers a rim opening that needs the look without a working key.
6) Can a 7-pin X Class plug be pinned into a 6-pin cylinder?
Not as a straight swap. The 606K79 is built as a 7-pin chamber plug, so it has to go into a shell drilled for 7 pins in the 3 inch mortise length. Mixing it with a 6-pin shell leaves chambers unaligned. Match the plug to the shell's pin count and length.
7) Will this plug work in a rim cylinder or an exit device cylinder?
No. It is cut for a threaded 3 inch mortise cylinder body. Rim cylinders use a different shell and a tailpiece rather than a cam, so for exit device work you want a rim cylinder, such as the Schlage 20-021 6-pin rim cylinder with vertical tailpiece cam or the 20-022 with the horizontal cam.
8) What about a deadbolt cylinder - can the 606K79 be used there?
No. The 606K79 is a mortise cylinder plug on the 57A2 Corbin Russwin keyway. Deadbolt work is covered by the Kaba Ilco 1549 Series key-in-deadbolt cylinder, and Medeco offers several deadbolt-oriented cylinders: the 1012040 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the 1065140 5-pin retrofit for Arrow JL interconnected locks and Emtek handlesets and deadbolts, and the 1075127 5-pin rim type lazy motion single cylinder for handlesets and deadbolts.
9) I need to re-key a key-in-knob or lever lock, not a mortise cylinder - what is the equivalent part?
The 606K79 plug fits 3 inch mortise cylinders only. For knob and lever bodies, the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, the 1599 Series is a key-in-knob replacement cylinder, and the 1579 Series is a knob and lever cylinder made for Sargent locks. The Falcon A23161-05 G is a key-in-lever cylinder with a 6-pin G keyway, keyed different with two cut keys.
10) I want a high-security or patented key option instead of the standard 57A2 plug - what are my choices?
The 606K79 is a 7-pin X Class plug on the Corbin Russwin 57A2 keyway. If the facility wants patented key control, the BEST 1CDF is a drill resistant preferred patented interchangeable core in 7-pin brass, 150 Series, and Medeco cylinders such as the 1065244 5-pin rim lazy motion with Emtek tailpiece fall in the same high-security family. Note that those are different key systems, so they will not key into an existing 57A2 master system.
11) Is this plug suitable for high-traffic commercial buildings like schools and hospitals?
Yes, it is a commercial-duty part, and the typical uses given are office buildings, schools, healthcare, government buildings, multi-tenant residential, industrial space and retail. For a facility standardizing on Corbin Russwin 57A2, keeping these plugs on the shelf lets a locksmith re-key in place instead of replacing whole cylinders.
12) Will an Emtek CY4 cylinder work as a substitute for the 606K79?
No. The Emtek CY4 is a residential-style replacement cylinder sold individually as an Emtek part. The 606K79 is a commercial 7-pin X Class plug cut for the Corbin Russwin 57A2 keyway and sized for 3 inch mortise cylinders, offered in 606 Satin Brass and 626 Satin Chrome. The two serve different lock platforms and different keying systems, so one does not drop into the other.
